IMPROVEMENT IN GRAIN AND GRASS-SEED SEPARATORS.

Specification forming part of Letters Patent No. 48,329, dated June 20,1865.

To all whom it may concern:

Be it known that I, JAMES B. WALLACE, of Franklin, in the county ofWarren and State of Ohio, have invented a new and Improved Grain andGrass-Seed Separator; and I do hereby declare that the following is afull, clear, and exact description thereof, which will enable othersskilled in the art to make and use the same, reference being had to theaccompanying drawings, forming part of this specification, in whichFigure l is a side elevation of my invention; Fig. 2, a plan or top Viewof my invention, the upper screen being partially broken away.

Similar letters of reference indicate like parts.

This invention consists in the employment or use of a series of screensconnected together and arranged within a frame in such a manner thatgrass seed and other foreign substances may be separated from grain, andthe grass-seed also separated from theworthless foreign substances.

A B 0 represent three screens, which are placed one over the other andconnected together by hooks and staples a, I). These screens areinclined from a horizontal position, and the upper one, A, is thelongest and the coarsest, being constructed of No. 8 wire. The centralscreen, B, is shorter' than A and finer, being constructed of No. 9wire. The lowest screen, 0, is the shortest and the finest, beingconstructed of No. 16 wire. These screens are supported by a squareshaft, D, which is between the screens A 'B, and the journals of thisshaft have their hearings in blocks E E, which are fitted in slots madevertically in upright posts F F, one being at each side of the screens.The blocks E E have ratchet-shaped teeth 0 made in their outer surfacesto receive the upper ends of springs G G, the lower ends of which aresecured to the posts F F. These springs G G support the blocks E E, andconsequently the shaft D and the screens; and the crank attached to oneof the journals of the former.

The grain passes down from the hopper J upon the elevated part of theupper screen, A, which is suflieiently coarse to let everything throughbut the wheat, which is discharged oti from the lower or depressed endof said screen. The central screen, B, receives the impurities whichpass through A, and the large cockle and defective grains of wheatdo notpass through B, and are consequently discharged from the lower ordepressed end of the same into an y-proper receptacle. The screen 0separates the grass-seed from the other coarser or larger articles, thegrass-seed passing through 0 and the other impurities falling from thelower or depressed end of the same.

The device may be constructed at a very moderate cost. It has beenpractically tested,

and operates well.

I claim-as new and desire to secure by Let ters Patent- The employmentor use ofa series of screens connected together, as shown, and suspendedwithin a suitable framing on a square shaft, which is supported byadjustable hearings or blocks E E, all arranged to operate in the mannersubstantially as and for the purpose herein set forth.
